In every scripture it is mentioned that man is the ideal of creation. In the Quran it is said, "We have made man the Caliph of the whole creation", in other words, the master of creation. The deeper we study life the clearer we see that life, under all its aspects, under all its names and forms, is constantly working towards the plane of the human being, helping the human being in his life's purpose which is to become God's instrument. One can see that camels, elephants and horses yield to the will of man. One sees that animals like dogs and cats, that birds like parrots and many singing birds, such as canaries, in time become satisfied even when imprisoned in a cage; in their captivity they can enjoy the companionship of man.
